Internal mobility in Polish companies: how to build a talent marketplace and reduce cost-per-hire by 50%

Acquiring a qualified specialist on the Polish labor market in 2026 costs on average between 12,000 and as much as 35,000 PLN, and the external recruitment process has extended to an average of 52 days. Internal mobility, supported by modern platforms like talent marketplace, represents the most effective way for organizations to radically reduce time and budget while eliminating the risk of cultural mismatch.

Most organizations make a fundamental mistake: they treat internal recruitment as a necessary evil or a simple job board on the company Intranet. The result? Top talent leaves for the competition because they only learn about development paths within their own company once they hand in their resignation. Building systemic internal mobility is not an HR project – it is a strategic operational business transformation.

What is Internal Mobility and why is traditional HR failing?

Internal mobility is the process of strategically moving talent within an organization – encompassing vertical promotions, lateral moves, reskilling, upskilling, and participation in cross-functional projects.

The traditional HR model was based on rigid job structures. The manager was the "owner" of the employee, and any attempt to move to another department involved an informal conflict of interest. In the face of dynamic technological changes, this model fails for three reasons:

1. Knowledge silos: Teams do not know what skills their colleagues on the next floor possess.
2. Hidden talent drain (Quiet Quitting): Ambitious employees, seeing no options for lateral movement, look for new challenges outside the structure.
3. High Cost-Per-Hire: Paying recruitment agencies for skills that the organization already possesses but cannot identify.

A holistic approach to mobility transforms a company from closed silos into a fluid ecosystem of opportunities. To understand the broader context of retaining key people in an organization, it is worth analyzing how to effectively manage employee retention on a limited budget.

Market context 2024–2026: Data and indicators that cannot be ignored

The numbers clearly indicate that external recruitment is becoming a financial burden for Polish enterprises.

• 50% reduction in Cost-Per-Hire: According to data from Gartner and the Josh Bersin Company, implementing a mature talent marketplace reduces the cost of hiring an employee by 45–55% compared to external recruitment.
• Retention Rate: Employees in companies with high internal mobility stay with the organization 41% longer on average (LinkedIn Learning Report).
• Time-to-Productivity: An internally recruited employee reaches full productivity in a new role within 14–21 days. For external recruitment, this period ranges from 60 to 90 days.
• Skills Gap: Over 60% of medium and large Polish enterprises identify a lack of visibility into internal skills as the primary barrier to executing new digital projects.

From Job Titles to Skills: How to Build an Effective Talent Marketplace

A Talent Marketplace is a platform (powered by AI algorithms and data analytics) that connects employees with internal career opportunities—projects, temporary gigs, mentorships, or full-time roles—based on their actual skills rather than their job title.

Step 1: Inventory and Skills Mapping

You cannot manage what you do not measure. The first step is to move away from job descriptions toward micro-skills. This involves creating a so-called skills architecture. We have outlined the precise methodology for this process in our report on implementing Skills-Based Organization models in the Polish market.

Step 2: Algorithmic Matching

A traditional job board requires the employee to actively search. A talent marketplace works like recommendations on streaming services: "Based on your knowledge of Python and Agile project management, you are an 85% match for the process transformation project in the Logistics department."

Step 3: Enabling Micro-Projects

Mobility is not just about a 180-degree career change. It is the opportunity to dedicate 10–20% of your weekly working hours to a project in another department. This gives the employee room to learn and provides the company with a quick solution to a business problem without hiring external consultants.

Comparing recruitment models: External vs. internal Talent Marketplace

Case Study: Transforming mobility in a Polish manufacturing and technology company (800 employees)

Initial situation:

A Polish electrical machinery company was planning to launch a new line of IoT products. The recruitment department estimated that acquiring 12 engineers and project managers from the market would take 8 months and cost approximately 380,000 PLN in recruitment fees and job postings alone.

Implemented solution:

Instead of going straight to the market, the management implemented a three-month pilot of internal competency mapping using HR data analytics. To learn more about measuring such processes, see our guide to People Analytics metrics for companies with 100 to 500 employees.

1. They identified 45 employees in the maintenance and R&D departments whose skills overlapped by 60–70% with the new requirements.
2. Dedicated reskilling programs were launched, combined with setting clear goals. The methodology for creating such paths is described in an article on how to effectively build professional development programs in a company.
3. The process was formalized by linking development plans with business goals. Details regarding this strategy can be found in a guide showing how to effectively set and monitor employee development goals.

Results:

• 8 out of 12 roles were filled internally within 45 days.
• Direct financial savings: PLN 230,000.
• Project launch time reduced by 3 months.
• Zero turnover among key engineers over the following 18 months.

The biggest mistakes and pitfalls in implementing internal mobility

Building a technical platform is only 20% of the success. The remaining 80% is organizational and management culture. Here is where companies most often fail:

1. Talent hoarding by managers

This is the most common barrier. A line manager, having a high-class specialist on their team, blocks their promotion or transfer to another department for fear of losing their own performance metrics.

• Solution: Include an internal mobility metric (as a % of employees moved to other departments) in the managers' own KPIs. A manager should be a talent promoter, not a jailer.

2. Lack of transparency and "cronyism"

If internal recruitment happens behind closed doors and information about vacancies only reaches a select few, it builds frustration and a sense of unfairness within the team.

• Solution: Every role and every gig project must be posted in a publicly accessible system with clear requirements.

3. Penalizing mistakes when trying something new

An employee who moves to a new department for reskilling and does not immediately achieve outstanding results is often stigmatized.

• Solution: Introduce a safe trial period (e.g., 3 months) with the option to return to the previous position without any loss of face.

How to start implementation in your company on Monday

1. Conduct an audit of internal recruitment processes: Check what percentage of vacancies from the last 12 months were filled by current employees. If the rate is below 20%, you are losing money.
2. Remove formal barriers: Eliminate rules like "you must work in one position for at least 2 years to be eligible for internal applications." Replace them with an assessment of competencies and real potential.
3. Launch a micro-project program: Identify 3 pressing problems in the company and announce them as 4-week projects requiring 5 hours per week for volunteers from any department.
4. Invest in supporting technology: Replace Excel spreadsheets with a dedicated tool that can automatically map skill gaps and suggest career paths.

Frequently Asked Questions (FAQ)

What is an organizational talent marketplace?

A talent marketplace is a platform that uses analytics and data to automatically connect employees with internal growth opportunities—such as new roles, temporary projects, mentoring programs, or training—based on their skill profiles.

How do you calculate the savings from internal mobility (Cost-Per-Hire)?

To calculate the real savings, subtract the total cost of internal recruitment (technology costs, HR time, potential onboarding training) from the total cost of external recruitment (recruitment agencies, job ads, lost productivity for 3 months, external onboarding costs). The difference is usually between 45% and 60% in favor of internal mobility.

Is every employee suitable for an internal mobility program?

No. Internal mobility requires a proactive attitude, a willingness to learn continuously, and flexibility. The organization's role is to create the infrastructure and opportunities, but the decision to grow and engage lies with the employee.

How do you convince managers to let go of the best people from their teams?

The key is to redesign the bonus system. Managers should be rewarded for developing talent that advances throughout the company. Furthermore, a manager who releases an employee to another department should have priority access to the talent pool from other units within the marketplace system.

How can you balance internal mobility with an employee's lack of time for their current tasks?

The best solution is percentage-based allocation. In a project-gigs model, an employee dedicates, for example, 10% of their weekly working hours (4 hours) to a development project. This requires aligning priorities with their manager and clearly defining the scope of responsibility.

Key takeaways

• Scalable savings: A mature internal mobility system cuts recruitment costs (Cost-Per-Hire) in half and reduces the time to fill a role from months to days.
• Skills over job titles: The future of HR lies in management based on real skills (Skills-Based Organization), rather than rigid job descriptions.
• Technology + Culture: Implementing a talent marketplace platform requires simultaneous work on a culture of talent sharing and eliminating defensive attitudes among management.
• Retention and Engagement: Giving employees the opportunity to evolve within the organization is the most effective vaccine against losing key talent to competitors.
